Commute really is key. When I used to have a 15-minute bike commute, I voluntarily went to the office five days a week. The 30 minutes spent each day is just good exercise.
Now I take the train that's 30 minutes long each way. I don't get the benefit of exercise, the time spent is doubled, and now I'm only going to the office three days a week.
